Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749458, here are decompositions:
- 7 + 8749451 = 8749458
- 19 + 8749439 = 8749458
- 37 + 8749421 = 8749458
- 41 + 8749417 = 8749458
- 101 + 8749357 = 8749458
- 127 + 8749331 = 8749458
- 149 + 8749309 = 8749458
- 229 + 8749229 = 8749458
Showing the first eight; more decompositions exist.
